I've read first hand accounts about what happened in Venezuela. About twenty years ago, Chavez turned a democracy into a dictatorship. How could this possibly happen?
Well, one ingredient was that the people who were against Chavez repeated over and over that the dictator was not logical.
In Venezuela, this type of argument did not persuade Chavez voters. It did the opposite. Chavez won and the country is now a dictatorship.
I see the same thing happening here. Trump supporters with a high school diploma are personally insulted when a bunch of PhD's get together and declare that their candidate is not scientific.
